use Lucifer - default settings - clear 9 stages (lost Eelis) [i thought for sure you had it, eelis is nasty. and wow this game actually looks nice with 16 bit color... could never get it to work right with my old comp. -skito]

All clear using galford Slash, changed setting to level 8 (hardest). Just a second try using a little trick at beginning (managed to get over 500000 pts. after first character with rimururu, so I guess she would be the way to go for best possible score if she can deliver a few more perfects).
